⚡ QR Code Technologies and Standards

EasyQRCodeJS library: we use the most modern JavaScript library that supports Canvas and SVG rendering. Provides full control over every element: Position Patterns (code eyes), Alignment Patterns, Timing Patterns, individual modules. Optimized for working with logos - automatically determines optimal size and position, uses intelligent placement algorithm considering error correction level.

ISO/IEC 18004:2015 standard: all generated QR codes comply with the international standard, guaranteeing 100% compatibility with all modern QR scanners and smartphone cameras iPhone and Android. The standard defines 40 QR code versions - from Version 1 (21×21 modules, up to 25 characters) to Version 40 (177×177 modules, up to 7089 digits or 2953 text characters). The generator automatically selects the optimal version based on data volume.

Reed-Solomon error correction levels: QR codes use Reed-Solomon error correction algorithms to recover damaged data. Level L recovers up to 7% of data (suitable for ideal conditions), M - 15% (standard use), Q - 25% (outdoor advertising), H - 30% (mandatory for QR with logo). The algorithm distributes redundant data so that even when removing the central part, the code remains readable. At level H, the logo can occupy up to 20% of the area without loss of functionality.

Canvas API technology: we use HTML5 Canvas API for programmatic logo overlay on QR code. The process includes: generating base QR code, loading and processing logo, scaling to optimal size 80×80 pixels for 300×300 code, adding white background around logo for contrast, overlaying exactly in center. Canvas API performs operations on client side without sending data to server - maximum speed and privacy. Supports transparent PNG logos.

🛠️ QR Code Optimization for Different Purposes

Size for different media: minimum size for reliable scanning - 2×2 cm at 300 DPI. For business cards - 1.5×1.5 cm (generate 300×300 px at 300 DPI), for flyers - 3×3 cm (500×500 px), for posters A3-A2 - 5×5 cm, for billboards - 10×10 cm and more. Golden rule: scanning distance = code size × 10. Code 3×3 cm scans from 30 cm, code 10×10 cm - from 1 meter. For websites 200-300 pixels are sufficient. For printing use 300+ DPI to avoid blurring.

Color scheme and contrast: contrast between code and background must be at least 60% for reliable scanning. Classic combination of black (#000000) on white (#FFFFFF) provides 100% contrast and best readability. When using brand colors, follow the rule: dark color for code (dark blue, dark green, burgundy), light for background (white, light gray, cream). Avoid yellow and light colors for code, dark background with dark code, gradients, transparency. Test colored codes on 5+ different devices before mass use.

Logo design: logo must be simple, contrasting and clear in small size. Optimal format - PNG with transparent background. Size no more than 20% of QR code area (for 300×300 px - logo 80×80 px). Shape: square or round. Add white border 2-3 pixels around for clear separation from code. Avoid fine details, thin lines under 2 pixels, gradients with low contrast. At 300 DPI, logo must be minimum 300×300 pixels to maintain quality when printing.

Print materials: matte surfaces (matte paper, cardboard) are ideal - no reflections. Glossy creates problems in bright light - use matte lamination. Transparent surfaces (glass, acrylic): place on opaque substrate. Textile surfaces: embroidery works at size from 5×5 cm. Metal: laser engraving on anodized aluminum. Critical: test after printing on final material under different lighting.

💡 Practical Tips for Creating QR Codes

Verification before use: mandatory test code on 3-5 different devices (iPhone different models, Android Samsung, Xiaomi, Huawei, tablet). Check different scanning apps - built-in iOS camera, Google Lens, special QR scanners. If printing - print test copy and scan from different distances (15-50 cm) and angles (straight, 30°, 45°). Ensure data correctness - link opens right page, Wi-Fi connects to right network, vCard saves correct contacts.

QR code placement: place at 120-160 cm height for comfortable standing scanning. Ensure sufficient lighting - minimum 300 lux. Avoid reflective surfaces, curved surfaces (flexible packaging, cones), surfaces behind glass with reflections. Add call-to-action text "Scan to connect to Wi-Fi", "Scan to view menu", "Scan to save contact".

Security and privacy: static QR codes store all information inside code - after download code works independently of website. For sensitive data use dynamic QR with ability to change information and scan analysis. When creating vCard include only necessary information. For commercial use comply with GDPR and data protection legislation.
